Mexican Exchange 

When something is defective or breaks on you when it's past the date of exchange policy or warranty, you buy another one of the exact same item and then return the damaged item using the new reciept.

*Explained to me by my Mexican-American friend.

Dude: Dang Bro, my USB flash drive just failed :-/

Bro: Dude, just buy another one from Amazon and return the dead one for a refund... it's called The Mexican exchange!

Mexican Border Exchange

The act of engaging orally with your partner, proceeding to extend your tongue into his/her mouth until touching the uvula. This will cause gag reflexes, and causing your partner to vomit into your mouth sending a satisfying waterfall of barf into your throat, exchanging back and forth.

"Hey man, what did you and that girl do last night?"
-"Not much bro, just a quick Mexican Border Exchange. She ate hotdogs!"
